Then another employee told me that the fuel is denser in the winter and so
the tank holds more.
News to me. I expect either dire warnings from you to either let out the
excess, or that this 76 station is in big trouble.

Oh.  That makes perfect sense (not).  The fuel is more dense.  Therefore it
takes 4.2 gallons (measure of volume) to fill a 3 gallon (measure of volume)
tank.  Yea.

If you purchased propane by the pound, and it normally took x pounds to fill
a given volume container, but in winter it is more dense, you would be able
to fit more than x pounds into the same volume container in winter.

However, we're dealing with volume / volume here.  To say that it's more
dense in winter is all well and good.  And maybe it is - so maybe there is
more potential energy contained in the 2.8 pounds you bought.  But to say
that the higher density allows 4.2 gallons to fit into a 3.0 gallon tank is
a crock.  4.2 gallons of *anything* has to be contained in a 4.2 gallon
tank.  This is so basic.  We're obviously not dealing with an intelligent
vendor, here.
